Motherboard *Standoff's?

I recently started my first build, about to get the case and put everything in it.What are the 'standoff's'?I know they are just screws with holes in them.Mainly to seperate two surfaces.

 

How do I go about ordering them?Should I just go to a hardware store?Did they come w/ my MoBo?I reaaaally can't short anything on my board so I need to learn real quick.

 

Thanks.
